We describe the importance of having low-energy (10-100 MeV) neutrino beams produced through the decay of boosted radioactive ions (“beta-beams”). We focus on the interest for neutrino-nucleus interaction studies and their impact for astrophysics, nuclear and particle physics. In particular, we discuss the relation to neutrinoless double-beta decay. Finally, we mention the status as far as the ...

Coal is largely composed of organic matter, but it is the inorganic matter in coal—minerals and trace elements—that have been cited as possible causes of health, environmental, and technological problems associated with the use of coal. Some trace elements in coal are naturally radioactive. These radioactive elements include uranium (U), thorium (Th), and their numerous decay products, includin...

General Information Tritium is the only radioactive* isotope of hydrogen and it is commonly represented by the chemical symbol H-3 or 3H. While the most common form of the hydrogen atom has a nucleus consisting of a single proton, tritium’s nucleus is comprised of three particles: two neutrons and a single proton. This configuration makes tritium’s nucleus unstable and tending to undergo a proc...

We describe an asymptotic analysis of the coupled nonlinear system of equations describing time-dependent three-dimensional monoenergetic neutron transport and isotopic depletion and radioactive decay. The classic asymptotic diffusion scaling of Larsen and Keller [1], along with a consistent small scaling of the terms describing the radioactive decay of isotopes, is applied to this coupled nonl...

The problem of utilization of high-activity waste by effect of nuclear transmutation in growing associations of microbiological cultures was studied. For the first time we have observed utilization of several kinds of highly active isotopes in the volume of distilled water extracted from the first contour of water-water atomic reactor convert to non-radioactive nuclei. 1. The model and the foun...

The Earth’s surface processes are predominantly controlled by the interaction between the Earth’s internal heat and solar radiation. Surface heat-flow measurements reflect the increase in temperature with depth, which results in flow of the Earth’s internal heat from the core, through the mantle, to the surface. Heat-flow is highest in volcanically active regions and is lowest near oceanic tren...

Nuclear Medicine (NM) is a medical imaging technique in which patients are administered radioactive tracers. As the tracers decay in the human body, they emit photons, which are then captured to generate an image used for diagnostic purposes. The schedule of daily patients in an NM center is a hard and interesting problem due to the continuous decay of these radioactive tracers. This scheduling...

The presented paper discusses the theory and results of direct experimental investigation of the control of internal electron conversion channel of radioactive isotopes spontaneous decay by controlling action of oriented crystal matrix on motion of conversion electrons. The same effect takes place at any β-processes (including at decay of a neutron with an emission of electrons and neutrino). I...

Emanation of radon (Rn) from several brands of cat (kitty) litter was measured with a continuous radon monitor. Radon emanating from the cat litters, encapsulated in an airtight container, produced equilibrium concentrations below 1.2 pCi/g. The measured radon flux was below 10 pCi/kg-hr for all the cat litters. Although each of the samples emitted a measurable amount of radon, the emanation is...

It is shown that a nontrivial quantum structure of our space at macroscopic scales, which may exist as a relic of quantum gravity processes in the early universe, gives rise to a new fundamental phenomenon: spontaneous origin of an interference picture in every physical process. This explains why statistical distributions in radioactivity measurements may be different from the Poisson distribut...
